Hmm, when talking about social circles, I would hesitate to say that there was any trick to it. Really all I could say is be the best person you could possibly be, get on good terms with as many people as you can from the social group and especially the guys that are already the top of the social circle. Just make sure you treat the top guys as equals to be befriended, not supermen to be won over.
Secondly, I think the idea of being the "top" of a social circle is slightly convoluted. In most of my groups of friends, there are people more or less liked by the other people, but I can't remember any occasions where one person has been somehow "above" the other people in his own social circle. In school, for example, the nerds all hung around together, so did the generally forgettables, the jocks, the punk/metal kids, etc. People generally hang around with people about their own level. What you should really focus on is getting in the best social circles.
